Question 847: Electrostats & Capacitance

Question

If the magnitude of intensity of electric field at a distance '$$r_1$$' on an axial line and at a distance '$$r_2$$' on an equatorial line due to a given short dipole are equal, then $$r_1: r_2$$, is

Accepted Answer

$$\begin{aligned}
& E_{	ext {axial }}=E_{	ext {equatorial }} \Rightarrow k \frac{2 p}{r_1^3}=\frac{k p}{r_2^3} \
& \Rightarrow \frac{r_1}{r_2}=\frac{2^{1 / 3}}{1}=\sqrt[3]{2}: 1
\end{aligned}$$

Answer

$$\sqrt[3]{2}: 1$$

Answer

$$\sqrt{2}: 1$$

Answer

$$1: 2$$

Answer

$$1: \sqrt[3]{2}$$
